3G

3G this is the name which is booming in India. India is going 3G as many I think almost all the telecom companies are starting the network which will deliver the 3G services to the Users/Customers of the Telecom company. The spectrum is sold by the Governing body of India TRAI. I know that its a much old thing in the world outside India but its still new to the people here in India and now some people in the metro cities are using 3G services.

What is 3G?

3G basically stands for 3rd Generation technology for mobile or cellular telephony which is also known as International Mobile Telecommunications-2000 (IMT-2000). It has some enhancements over the previous versions such as high speed, global roaming, advanced multimedia access etc.

Specifications of 3G

It is following the pattern of generation that is created by the ITU (International Telecommunications Union). 3G network has a speed which varies and depends on the speed of the user. ie the moving speed of the user. If the user is walking then it will be around 384kbps and if user is on fast moving vehicle then it will be dropped to the 128 to 144 kbps. The speed me go beyond 2mbps  on certain enviornment.

Main Features of 3G

  • The speed is enhanced much more time as compared to previous versions.
  • It increases the bandwidth.
  • We can watch TV through internet.
  • Enhanced video streaming.
  • Supports video conferencing.
  • Web can be browsed at higher speeds.

What we need?

To access 3G we need a mobile device which has 3G functionality in it. It doesn’t matter with the number and position of camera or the operating system the phone has. It must be a 3G compatible phone. there can be 2 cameras(rear and front) on such phones because this allows video calling.

you can connect to 3G network via a sim card or the 3G data card which are sold by service provider.

Speed up your symbian phones

Nokia phones… (Symbian Phones)

Till now Nokia Inc are the boss of the Mobile world that is in selling handsets. So many of us are using Nokia phones. Nokia bought Symbian Inc in 2008 and then started developing OS for its phones and the main problem is that after some months the phones get slower and slower which is very irritating for the users.

So here is something to cheer about and be happy because there are some ways to deal with such slow phones and we are discussing them here.

there are various options such as Memory Management, 3rd party tools, and a trick within your phone.

The very common reason is that people put so much of data in that little phone that it cant handle. Though your phone has lot of internal memory try not to fill it with large amount of data or pictures, sound clips or video clips of large size, always store them to external memory stick so that it can be organized and handled efficiently.

now coming towards 3rd party tools for memory management and to for JVM of phone which takes control of JVM and analyzes all programs running in background.and there are various other 3rd party tools to clean registry and applications and cache memory of the phone to remove installed application we can try those other softwares too to get more from our nokia symbian phones.

there is another trick

  • set the phone’ date to 01.05.2005.
  • Navigate to the calender application and create 2 new to do
  • now set the following parameters in each of them
    To-do
    subject: speed
    due date: 04.08.2005
    priority:high 

    To-do
    subject: Quokie
    due date: 04.08.2005
    priority:Low

  • confirm both the notes as done and leave that calender application
  • Now revert the date of the phone.
  • The game is done the phone will start working fluently and you can feel the difference.

So guys enjoy the tricks and if you have any other good tricks then please add them in your comments.

Symbian OS

Dear Friends I’m back today with yet another topic for you.

Today I’m going to explain you something about Symbian OS what was it before a Symbian OS and how it is evolved?

Nowadays we all own a cellphone does anybody think that there can be an operating system in the mobile phones? OK leaving that question apart today there are various different kind of smart phones are available in market (there is a long lasting list). So all these smart phones run on some operating system viz iOS(Apple smart phones), Maemo(Linux based OS), Symbian, Java, Android, Windows Mobile etc.

Symbian is the descended from the EPOC family of operating system which is developed for Portable Devices by Psion. There were various version of EPOC in the market. In 1998 Psion Software became Symbian Ltd with the Nokia, Motorolla and Ericsson. and after which the next release of the EPOC was named as Symbian OS though this was first symbian os still its version was 6.0 then the next version was 6.1 and other various versions were launched 7.0 , 8.0 ,9.0 to 9.5 but the revolution was 9.2 which was used in Eseries and Nseries phones. Now the latest version of Symbian is Symbian^3.

Security is one of the most important criteria in an operating system.Symbian OS was subject to a variety of viruses.However, with a view that the average mobile phone user shouldn’t have to worry about security.

Symbian was the first platform specifically developed for smartphones – it started the smartphone revolution and remains at the heart of the people. The Symbian platform is used by more people in more places than any other mobile OS, making Symbian the most popular smartphone platform on the planet.The Symbian platform gives you the power to do more with mobile. The code of symbian is freely available so anyone can redesign and build the operating system for mobile device. Symbian OS are packaged in .sis format and can be installed by any way which is available bluetooth, via PC etc. In 2008 Symbian Ltd was acquired by Nokia and new independent Symbian Foundation was established.

The Symbian OS features multitasking and storage protection, to save the time and the most important is security of data.Symbian uses a microkernel, has a request-and-callback approach to services, and maintains separation between user interface and engine. The OS is optimised for low-power battery-based devices and for ROM-based systems.

Symbian devices can also be programmed using Python, Java ME, Flash Lite, Ruby, .NET, Web Runtime (WRT) Widgets and Standard C/C++.As of 2010, the SDK for Symbian is standard C++, using Qt. It can be used with either Qt Creator, or Carbide A phone simulator allows testing of Qt apps. Apps compiled for the simulator are compiled to native code for the development platform.

Bluetooth

Bluetooth This one of very commonly used word now a days in our life.

We must have heard this thing from various links our friends,collegues and other sources such as tech mags. So lets read soemthing about it..

Whenever we listen to a nice or one of our favorite song on our friend’s cellphone or an image or wallpaper or want to receive some data from other’s mobile device. So lets elaborate it.

Bluetooth can be termed as a device which is used for transfer of data within short distances.Bluetooth wireless technology enables us to secure, robust and wireless connection between mobile devices and fixed devices. In other words “Bluetooth wireless technology is built into electronic gadgets and lets you talk and share information like voice, music, and videos wirelessly.” While transferring the data from a mobile device to another mobile device it creates a PAN (Personalized Area Network) and allows us to connect various devices. It was created by telecom company Ericsson in 1994.

The Name – The name “Bluetooth” is actually very old! It is from the 10th century Danish King Harald Blatand – or Harold Bluetooth in English. King Blatand was instrumental in uniting warring factions in parts of what is now Norway, Sweden and Denmark – just as Bluetooth technology is designed to allow collaboration between differing industries such as the computing, mobile phone and automotive markets.

Bluetooth uses a radio technology called frequency-hopping spread spectrum, which chops up the data being sent and transmits chunks of it on up to 79 bands (1 MHz each) in the range 2402-2480 MHz. This is in the globally unlicensed 2.4 GHz short-range radio frequency band.Bluetooth provides a secure way to connect and exchange information between devices such as faxes, mobile phones, telephones, laptops, personal computers, printers, Global Positioning System (GPS) receivers, digital cameras, and video game consoles.The Bluetooth specifications are developed and licensed by the Bluetooth Special Interest Group. The Bluetooth SIG(Special Interest Group) consists of more than 13,000 companies in the areas of telecommunication, computing, networking, and consumer electronics.

Bluetooth is a protocol which is connected in master slave connection and a master can communicate with almost 7 slaves creating a network which is called as piconet.In this piconet each slave can anytime switch its role and become master. Just like an internet connections 2 piconet can also connected to each other.

Now a days bluetooth is provided in various devices such as telephones, cellphones, WIFI, playstations, PSPs, modem, printers, iPod touch, watches etc. This is used between a mobile phone and its headset, various PC input and output devices very common names are mouse,keyboards, printers. It replaced the serial wired connection and places controlled by infrared. If your personal computer do not have embedded bluetooth connection then you can use bluetooth dongles for that purpose. Apple provided support for bluetooth in 2002 in its Mac OS X. and windows in its Windows XP sp2 and sp3.

The various version of bluetooth are:

1)v1.0 , v1.0B

2)v1.1 – This removed various drawbacks of version 1.0B

3)v1.2 – This was compatible with 1.1 and with faster connection and searching of devices

4)v2.0 + Enhanced Data Rate – This is with enhanced data rate for the faster transfer of data with the theoretical speed of almost 3mbps but the actual speed was 2.1mbps

5)v2.1 + Enhanced Data Rate – The main features of this is Secure Simple Pairing, reduction in power consumption in low frequency mode

6)v3.0+HS – This version has the theoretical speed of about 24mbps.

7)the Bluetooth SIG completed the Bluetooth Core Specification version 4.0, which includes classic bluetooth , bluetooth high speed and bluetooth low energy protocols. Bluetooth high speed is based on WiFi, and Classic Bluetooth consists of legacy Bluetooth protocols.

Bluetooth technology was originally intended to be a wireless replacement for cables and wires between things like phones and headsets or computers, keyboards and mice. It works great in those devices and it can do so much more—connecting TVs, music players and even home devices.
